Cow Pat Pit
Cow Pat Pit (CPP) is a biodynamic preparation that stimulates soil activity and enhances the humus forming processes of the soil. It also helps to initiate the fermentation of manure and activates organic matter conversion in compost. Research carried out after the Chernobyl disaster showed how it helped reduce the effects of radioactive fallout on land where it was applied.
It is made by mixing cow manure with crushed egg shell and basalt dust, which is then fermented with biodynamic preparations 502-507 for a three to four months in a 12 inch deep pit lined with bricks.
Unfortunately we didn't get around making our own CPP this year, but instead have sourced some from the Biodynamic Association which we have added to a compost pile that will be spread on the vineyard in the next few weeks. This will help address deficiencies some nitrogen and minerals deficiencies which were identified by a petiole analysis earlier in the year. Biodynamics and science working in harmony!
